President Donald Trump has signed a new presidential proclamation tightening entry rules into the United States, extending partial travel restrictions to 16 additional countries, including Nigeria.

The measure was approved on Tuesday, according to official statements, and forms part of what the administration describes as continued efforts to strengthen US travel and border security standards. The decision broadens an existing framework that screens foreign nationals based on security cooperation, identity management, and information-sharing benchmarks.

Countries newly placed under partial restrictions

Under the latest order, partial limitations now apply to citizens of Angola, Antigua and Barbuda, Benin, Côte d’Ivoire, Dominica, Gabon, The Gambia, Malawi, Mauritania, Nigeria, Senegal, Tanzania, Tonga, Zambia, and Zimbabwe.

According to the proclamation, these restrictions vary by visa category and are intended to address concerns identified during recent security and compliance reviews.

Full bans remain and expand

The order maintains full travel restrictions on 12 countries previously designated as high risk. These are Afghanistan, Burma, Chad, the Republic of the Congo, Equatorial Guinea, Eritrea, Haiti, Iran, Libya, Somalia, Sudan, and Yemen.

In addition, five more countries have now been placed under full restrictions following updated security assessments. They are Burkina Faso, Mali, Niger, South Sudan, and Syria. The proclamation also applies full restrictions to individuals traveling on Palestinian Authority issued travel documents.

Two countries that were earlier subject to partial limits, Laos and Sierra Leone, have been moved to the full restriction category. Meanwhile, partial restrictions remain in place for Burundi, Cuba, Togo, and Venezuela.

Limited relief for Turkmenistan

The proclamation lifts the ban on nonimmigrant visas for Turkmenistan. US officials cited improved cooperation with American authorities as the basis for the change. However, restrictions on immigrant visas for Turkmen nationals remain in force.

Exemptions and special cases

The administration outlined several exemptions within the order. Lawful permanent residents of the United States are not affected, nor are individuals who already hold valid visas. Certain visa classes, including those issued to diplomats and athletes, are also exempt.

The proclamation further allows entry for individuals whose travel is deemed to serve US national interests, according to the document.

Reactions and broader implications

Travel policy analysts say the expanded list could have diplomatic and economic consequences, particularly for countries with strong migration and business ties to the United States. According to immigration experts, the practical impact will depend largely on how consular officers implement the new rules and how narrowly exemptions are applied.

The White House has not indicated whether additional countries could be added in future reviews, but officials say security evaluations will remain ongoing.
